The Boot JDK detection# process has been developed as a response to solve a complex real-world# problem. Initially, it was simple, but it has grown as platform after# platform, idiosyncracy after idiosyncracy has been supported.## The basic idea is this:# 1) You need an acceptable *) JDK to use as a Boot JDK# 2) There are several ways to locate a JDK, that are mostly platform# dependent **)# 3) You can have multiple JDKs installed# 4) If possible, configure should try to dig out an acceptable JDK# automatically, without having to resort to command-line options## *) acceptable means e.g. JDK7 for building JDK8, a complete JDK (with# javac) and not a JRE, etc.## **) On Windows we typically use a well-known path.# On MacOSX we typically use the tool java_home.# On Linux we typically find javac in the $PATH, and then follow a# chain of symlinks that often ends up in a real JDK.## This leads to the code where we check in different ways to locate a# JDK, and if one is found, check if it is acceptable. If not, we print# our reasons for rejecting it (useful when debugging non-working# configure situations) and continue checking the next one.######################################################################### Execute the check given as argument, and verify the result# If the Boot JDK was previously found, do nothing# $1 A command line (typically autoconf macro) to executeAC_DEFUN([BOOTJDK_DO_CHECK],[ if test "x$BOOT_JDK_FOUND" = xno; then # Now execute the test $1 # If previous step claimed to have found a JDK, check it to see if it seems to be valid. if test "x$BOOT_JDK_FOUND" = xmaybe; then # Do we have a bin/java? if test ! -x "$BOOT_JDK/bin/java"; then AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/java; ignoring]) BOOT_JDK_FOUND=no else # Do we have a bin/javac? if test ! -x "$BOOT_JDK/bin/javac"; then AC_MSG_NOTICE([Potential Boot JDK found at $BOOT_JDK did not contain bin/javac; ignoring]) AC_MSG_NOTICE([(This might be an JRE instead of an JDK)]) BOOT_JDK_FOUND=no else # Oh, this is looking good!
